为探讨在黄斑裂孔手术中安全有效使用过氟化碳气体（Ｃ２Ｆ６、Ｃ３Ｆ８）的方法，对３１例黄斑裂孔患者进行玻璃体切割、气液交换、随机分３组分别在不同眼压控制下进行长效气体填充。结果：随访１～４个月，总的解剖成功率为８３．９％，术中气泵压力在１５～１７ｍｍＨｇ下，眼内注射０．６～０．８ｍｌ过氟化碳气体，术后眼压基本平稳。高峰期在术后２４小时，药物可以控制。结论：过氟化碳气体填充要保障安全量和有效气体浓度
To investigate the safe and effective use of perfluorocarbon gas (C2F6, C3F8) in macular hole surgery, 31 cases of macular hole patients underwent vitrectomy and gas-liquid exchange. Randomly divided into three groups, Effective gas filling. Results: The follow-up of 1 to 4 months, the total success rate of 83.9% anatomy, intraoperative air pump pressure 15 ~ 17mmHg, intraocular injection of 0.6 ~ 0.8ml perfluorocarbon gas, postoperative intraocular pressure Basically stable. 24 hours after the peak, the drug can be controlled. Conclusion: Fluorocarbon gas filled to ensure safety and effective gas concentration
